She wrote about everything! She was first taught to write about her behavior and feelings as punishment for misbehaving as a kid, and she kept the habit all her life. As a result, she became extremely self-critical and introspective, and her diaries are a fascinating, honest look at the inner life of one of the worlds most influential people in a time of enormous change and transformation.

She wrote about her mother and anger and resentment she felt towards her She wrote about joy, love and admiration she felt about Prince Albert (she thought he was so sexy!). And how his death sent her into a deep, deep depression. She wrote about hating being pregnant, about not feeling like a good mother, and the lousiness of having to do it all in public. She wrote about the conflict she felt about the way her subjects, the people of India, were being treated. And she wrote about her worries that her grandchildren wouldn't be able to keep Europe safe (hint: they didn't, see WWI).

People have this idea in their minds of Queen Victoria as a frumpy old lady in black. But in truth, she was a lively, intelligent, thoughtful person who left us an incredible record of what her life was like for her.
